Within an EP11 cprb there exists a byte field flags. Bit 0x20
of this field indicates a special cprb. A special cprb triggers
special handling in the firmware below the OS layer.

However, a special cprb also needs to have the S bit in GPR0
set when NQAP is called. This was not the case for EP11 cprbs
and this patch now introduces the code to support this.
